The Lichens They are strange symbionts, a partnership between one and the other Fungus It is shelter, water and minerals and Microgreen algae or cyanobacteria They provide food from their photosynthesis. And while they may not be particularly interesting to look at, lichens are incredibly tough They can survive even in the harsh environment of space.
As stated GuardianWhen lichens cling to its exterior International Space Station for 18 monthsSurviving in the vacuum of space, without water, with extreme temperatures and under the full onslaught of radiation and ultraviolet rays from the sun, it continued to photosynthesize.
Lichens are preserved in a simulated environment Mars planet On Earth, they survived and were active, multiplying them Life opportunities On the Red Planet, the environment is extremely dry and cold, with low atmospheric pressure and radiation bombardment.
Lichens are true They can withstand 12,000 times the lethal dose for humans and continue photosynthesis, although their reproduction may suffer. On the other hand, bacteria that received the same treatment died in experiments.
There is even the possibility of life on Earth or any other planet spread through space From lichens carried by meteors, comets, or asteroids.
